What is Open Interest?
Open Interest (OI) is the total number of outstanding derivative contracts — futures or options — that have not been settled or closed. Unlike trading volume, which resets daily, open interest accumulates over time and reflects the total amount of capital actively committed to a market.
Why Open Interest Changes Matter
- Rising OI + Rising Price — New money entering long positions; confirms a bullish trend
- Rising OI + Falling Price — New money entering short positions; confirms a bearish trend
- Falling OI + Rising Price — Short squeeze; potentially unsustainable rally
- Falling OI + Falling Price — Long liquidations or profit-taking; bearish trend losing steam
Practical Applications
- Identify overleveraged markets — extremely high OI signals fragility and liquidation cascade risk
- Validate breakouts — a breakout on rising OI is significantly more reliable than one on declining OI
- Monitor whale positioning — sudden OI spikes often indicate institutional activity
